Abstract
A unitized component assembly includes an component having an aperture, and a plurality of discrete projections extending into the aperture and spaced apart from one another about the perimeter of the aperture, and a fastener having a head and a shank extending from the head. The shank includes a necked portion and a threaded portion adjacent the necked portion. The shank is positioned in the aperture such that the necked portion is in facing relationship with the projections. The threaded portion is engageable with the projections to provide an axial stop for limiting movement of the fastener relative to the component
Claims24
A unitized component assembly comprising:
- a component including an aperture and a plurality of discrete projections extending into the aperture and spaced apart from one another about the perimeter of the aperture;
- and
- a fastener including a head and a shank extending from the head, the shank having a necked portion and a threaded portion adjacent the necked portion, the shank positioned in the aperture such that the necked portion is in facing relationship with the projections;
- wherein the threaded portion is engageable with the projections to provide an axial stop for limiting movement of the fastener relative to the component.
A method of unitizing a fastener and a component, the method comprising:
- providing the component with an aperture and a plurality of discrete projections extending into the aperture and spaced apart from one another about the perimeter of the aperture;
- providing the fastener with a head and a shank having a necked portion and a threaded portion adjacent the necked portion;
- inserting the shank into the aperture;
- at least partially deforming each of the projections during insertion of the threaded portion of the shank into the aperture;
- positioning the necked portion of the fastener in facing relationship with the projections after the projections have been deformed by the threaded portion of the shank;
- and
- engaging the threaded portion of the shank with the projections to provide an axial stop for limiting movement of the fastener relative to the component.
